LM2840 - Step-Down DC/DC Regulator

Description

The LM284x SIMPLE SWITCHER™ devices are PWM DC/DC buck (step-down) regulators.

With an input range from 4.5 V to 42 V, they are suitable for a wide range of applications, such as power conditioning from unregulated sources.

Features

  • 1 Input voltage 4.5 V to 42 V.
  • Output current options of 100 mA, 300 mA, and 600 mA.
  • Feedback pin voltage of 0.765 V.
  • 550-kHz (X) or 1.25-MHz (Y) switching frequency.
  • Low shutdown IQ: 16-µA typical.
  • Short-circuit protected.
  • Internally compensated.
  • Soft-start circuitry.
  • Small overall solution size (SOT-6L package).
  • Create a custom design using the LM2840 (or LM2841/42) with the.
